"the anterior branch typically contains all L3 fibres of the nerve and terminal branches are distributed along the anterolateral surface of the thigh with terminal twigs also donated to the patellar plexus"
"the posterior branch typically contains all L2 fibres and continues down the posterolateral aspect of the thigh along the iliotibial tract contributing terminal filaments that pass across the lateral and posterior surfaces of the thigh"
"The lateral femoral cutaneous nerve, like the femoral nerve, is formed from the posterior divisions of the anterior rami of L2 and L3 spinal nerves. It courses on the anterior surfaces of the iliacus muscle after becoming secured in the fibrous sheath overlying the iliacus muscle, the iliac fascia. The nerve passes under the lateral aspect of the inguinal ligament, in a compartment sometimes called the muscular lacuna, approximately 10-15 mm medial to the ASIS to lie on the anterior surface of the sartorius muscle and deep to the fascia lata. Both the anterior and posterior divisions of the nerve eventually pierce the fascia lata to give terminal cutaneous branches."

"meralgia paraesthetica: the lateral cutaneous nerve of the thigh is sometimes compressed as it passes under the inguinal ligament or occasionally where it pierces the fascia lata and may cause pain in the lateral aspect of the thigh; decompression of the nerve may be required"
